Speciflcation'of Letters Patent.

Application filed September 25, 1908. Serial No. 454,677.

To all whom it may concem:

Be it known that I, EDOUARD/C. DAD- LEINE, a citizen of the Republic of France,

and a resident of the city of New York, bormg? of Manhattan, in the county and State of ew York, have invented a new and 1mprovcd Coil'ceUm, of which the following is a full, clear, and exact description.

The invention is an improved coffee urn in which the water under steam pressure is. nutornetically distributed over the coffee and percolatcs therethrough and then passes into the coffee pot, where it is maintained near but always slightly below the boiling ioint.

To this end the invention in general consists of a boiler, a coffee pot seated on the boiler, a coffee container seated on the coffee pot and having a perforated bottom, and a tube leading from a oiht below the normal liquid level In the boiler to a. point above the coffee in the container.

Reference is to be had to the accompanying drawings forming a part of this specification, in wlnch similar characters of reference indicate corresponding parts in both views.

Figure 1 is a central vertical section of a coffee urn embodying my invention; and Fig. 2 is a cross-section of the some substantiall on the line 2-2 of Fig. 1.

T e invention essentially consists of a boiler 5, :1- cotfee pot 6 and a coffee container 7 which are shown to be arranged one abo e the other, with the boiler at the bottom, the z quired to maiie the amount of coffee wanted.

container at the top and the pot occupying an intermediate position and having a faucet 8 near its bottom for drawing off the coffee. The boiler 5 is shown to be supported at a substantial elevation by legs 9, and has the general shape of a kettle with handles 10 arranged at opposite sides. At one side of the boiler a. vent or plug 11 is provided, which is acted on b the steam pressure through a tube 12 which leads from a. point above the normal. water level. The neck of the boiler is shown to be constructed with an inwardly rejecting flange 13, sh htly depressed beow its top edge, on whic 1 seats the reduced bottom portion of the pot 6, this portion of the pot closely'fitting the boiler and.forming in connection therewith asubstantinlly may be lessened by partly opening the vent steam-tight joint.

In order to carry out the ornamental effect of the urn, the 0t 6 is preferably in the form of a globe, and lists an open upper end skirted by a flange 14 which receives the reduced portion 0 the container 7, the shoulder 14 l i i l Patented April 26, redo.

produced by said reduced portion seating on the top edge of the flange 14. The continue:

7 has a reticulated or perforated bottom 15,-"

and o dome-shaped cover 16.

From the center of the pot 6 rises an upright tube 17, and over the u or end of this tube telescopes the exponde ower end of a similar tube 18, the latter being rigidly see cured to the bottom of the container 7 and provided at its upper end, within or near the dome cover 16, with a hood 19. A tube 20 is detochably engeged within the tube 17 and snu 'ly fits the same, as also the tube 18, and lcots from a point below the normal water level in the boiler to a point slightly below the hood and above the coffee in the con tainer, at which point it has a perforated end 21. coffee pot mo. be carried out in any desired manner, which, in the present form of the invention, is shown to be effected by constructing the lower end of the tube 17 of conical wit a corresponding conical portion 22.

The construction of the urn as shown and described admits of the separation of the three princi el warts, also a removal of the tube 30, wiiere y the entire urn may be thorou hly cleansed after using.

Intiie use of the urn, the boiler is filled with w'ster to about the level indicated and within the coffee container is laced the quantity of round or pulverize coffee re- Suitable heat, as an alcohol lump or other burner, is then applied to the boi er, and as the steam pressure sufficiently uses it forces the boiling: water through the tube 20, and

11, or the flow may be entirely stopped through the tube by removin this plug, in

which case the steam from t e boiler will pass out through the time 12. Ordinarily the vent will be slightly opened during the shape and providing the tube 20 at its point nm kin of the cofi'ec, unless the o )emtion is to Y; "itstenetiin which event t e plug is screwed in tight. N-0 .metter how fast the steam is generated in the bdilelgthe coffee in the coffee pot never boils but is always 11minteined below a boiling temperature.

Having thus described my invention, I clainles new and desire to secure by Letters Patent:

1. The combination of a water receptacle, n cofl'eepot seated on the receptacle and having a fixed upri h seated on the cpi fee pot'end having a perforated bo bUlll, am upright tube fixed to the bottom 0 the COlltltlllCl and telescoping over the tubein the pot, a hood carried at the up Jer end of the tube within the container, and a tube leading from the receptacle to a point slightly below said hood and closely fitting the first mentioned tubes.

2. The combination of a boiler, a coil'ee pot the cofl'ec pot, bottom thereof and 1 per end of the first mentioner tube, and a tubes and t tube, a coffee container seated on the boiler havin I a tube rising from the bottom thereof, with that portion of the tube adjacent to the bottom of the pot of conical form, a coflee container seated on having a tube attached to the telescopin over the uptube passing from u point near the bottom of the boiler to a point near the top of the coffeecontainer, closely fitting the first mentioned having a. conical member fric tlflllltlly engaging in the conical lower end oi the first mentioned tube.

In testimony whereof I'have signed nume to this specification in the two subscribing witnesses.
